ducit

ducIt is a modular, web-based platform designed to help individuals and teams create, organize, and navigate interconnected documents and data. The system emphasizes bidirectional linking, citation tracking, and collaborative editing, enabling users to build knowledge graphs from notes, reports, and research sources.

Origins and governance: The project originated in 2017–2019 as an open-source effort led by a community of researchers and developers. It is maintained by the DucIt Foundation, which oversees core releases, security updates, and a plugin ecosystem. The project is released under the MIT license.

Features: Core features include a graph-based document model, bidirectional links, citation trails, tagging and annotations, advanced search, version history, and offline access. It offers import/export in Markdown, BibTeX, and JSON; a REST and GraphQL API; and a plugin architecture to extend editors, importers, and visualizations.

Architecture and deployment: The back end is composed of microservices with a graph database as the primary storage. A front-end client provides a responsive single-page app. Data is stored in a relational store for metadata and a graph store for relationships. Deployment is supported via Docker containers and cloud services.

Reception and use: ducIt has found adoption in academic research, policy documentation, and content teams seeking to map ideas and sources. Critics point to the learning curve and the maturity of the plugin ecosystem, while supporters highlight strong search, traceability, and collaboration features.
